Reserve a handful of crust for topping.Place sliced apples in large bowl. Drizzle with lemon juice and sprinkle with spices; toss until well coated. Add the lemon rind, sprinkle in the flour, and mix again. Gradually add the sugar or honey (and optional sour cream) as you mix. Don't worry if the apple slices break a little while being mixed and tossed.Distribute the filling into the unbaked crust. Sprinkle the handful of reserved crust mix over the top, with or without the optional extra nuts, and pat neatly into place.Bake 40-45 minutes, or until the apples are soft and the crust is nicely browned on the edges.
